NCO Problems

Can I implement this form of sequence with NCO,S(nT)=Asin(2πfn²T)，That is, whether the phase increment changes along each clock hop. Thank you in advance for your help.

Just had a chance to look at IP core ; looks like it is possible using NCO to generate the sine in terms of pulsed sine .

Kindly let me know if you have any question further for the same ?

    It means that NCO IP core can implement the form S(nT)=Asin(2πfnT), but it's not certain that S(nT)=Asin(2πfn²T) in this case.
